Speaks Words of Wisdom... On occasion
That sounds like they do the same thing? Is it double-risky to use both the Sorcery domain and the Sorcery On option for the same action?
Hmm, let me elaborate further.
"Sorcery as a Domain" is invoked with Favor when the action you're taking works nicely with it, and represents the VM empowering Sorcerous actions taken in support of that project, so that they get more bang for each little spell and ritual.
Sorcery the Effect is a toggle you can turn on or off for whatever. Which represents bringing in extra specialists who are authorized to use magic and have them do it for your sake. Sorcery the Domain happens when you need them to begin with, but the implication is that they're doing a lot of risk mitigation and only bringing in the best of the best instead of the merely good.
